- SPECIFICATION forming part of Letters Patent No. 10,509, dated June 4, 1895.

' Application filed October 3, 18944, Serial No. 524,784- (No model.)

To all whom it may concern: H connected by a belt with other machinery Be it known that we, HARRY KIME MoW-. for imparting a rotary motion to the said SON and ROSWELL FREDERICK COREY, of shaft H and the eccentrics H, to actuate the Scottsville, in the county of Monroe and State eccentric heads G. The latter are rigidly 5 of New York, have invented a newand Imconnected by eccentric rods I, with the sides proved Shaking-Bolt, of which the following of the sieve C at the connection of the rods is a full, clear, and exact description. .B with the said sieve, so that the eccentrics The invention relates to graders; and its H, by the said rods I, impart a longitudinal 6o object is to provide a new andimproved shakshaking motion to the sieve C, and by the [0 ing bolt, which is simple and durable in conrods G, rocking beams E and rods D, an up struction and arranged to combine a scalper and down motion' is given to the upper end with a grader, to properly and rapidly bolt of the sieve. Thus, a double motion is imlarge quantities of the Various products, such part-ed to the sieve, to readily agitate the maas break chop, middlings and flour, without terial passing over the sieve, the said material 15 danger of clogging. n being introduced on the sieve at the upper The invention consists of certain parts and end thereof.

The sieve C receives 10o trio heads G engaging the eccentrics H, a longitudinal motion and an up and down 50 formed on the transversely extending-shaft'H motion at the upper end from a mechanism mounted to turn in suitable bearings on the identical with the one above referred to and frame A, and. carrying at one end a pulley used for agitating or shaking the sieve. This a device for imparting motion to the sieve C is set in motion by eccentrics on a shaft 1-1 mounted to turn in suitable bearings at the end of the frame A, the said shaft H being provided with a sprocket wheel H connected by a belt or chain 11 with a sprocket wheel H, secured on the shaft l-l, so that the rotary motion of the latter is transmitted to the shaft H and consequently, the sieve O is agitated simultaneously with the sieve G and in the same manner.

In order to clean the meshes of the sieve bottoms, we provide the sieve O with arevoluble brush Q, mounted to travel under the said perforated bottom and rotating at the same time, so that its bristles readily clean the meshes of any flour filling the said meshes. A similar revoluble and traveling brush Q is arranged under the perforated bottom of the sieve C, and both revoluble brushes are preferably of the construction shown and described in the application for Letters Patent, Serial No. 517,099, filed by us on the 10th day of July, 1894. The mechanism for operating the brushes is identical to the one described in said application, so that further description of the same is not deemed necessary, it being however, understood that the actuating mechanism for the brushes Q, is driven from the shaft H, and the shaft l'l drives the mechanism for the brush Q.

It is further understood that it is not absolutely necessary to employ two sieves O and C, but in order to produce a very fine grade of flour, two or more such sieves are preferably employed.

Having thus fully described our invention, we claim as new and desire to secure by Letters Patent- 1. A shaking bolt, comprising a sieve held in an inclined position, rods supporting the lower ends of the sieve, rocking beams connected with the upper ends of the said sieve, a driving shaft eccentrically connected with the said beams, and also eccentrically connected with the lower ends of the said sieve, substantially as shown and described.

2. A shaking bolt, comprising a sieve held in an inclined position, rods supporting the lower ends of the sieve, rocking beams connected with the upper ends of the said sieve, means, substantially as described, for imparting a longitudinal shaking motion to the said sieve and a swinging motion to the said beams, a hopper provided with a movable feed gate operatively connected with the said beams, and a feed board upon which is discharged the material issuing from the hopper, to feed the material into the upper end of the sieve, as set forth.
